XD74LS151 – Multiplexer / Data Selector – Xinluda

The Xinluda XD74LS151 is a 1-of-8 line data selector/multiplexer in the 74LS low-power Schottky TTL family, supplied in a 16-pin DIP package with complementary Y and W outputs and an active-low strobe (enable).

The XD74LS151 from Xinluda is a member of the venerable 74LS (low-power Schottky TTL) logic family, implementing the industry-standard 74LS151 function: an 8-line to 1-line data selector/multiplexer. The device uses full on-chip binary decoding of three select inputs to route one of eight data inputs (D0 through D7) to the output. An active-low strobe (enable) input allows the device to be disabled or used for output expansion, and the part provides both a true output (Y) and its complement (W).

As a drop-in functional equivalent to the classic SN74LS151 / DM74LS151, the XD74LS151 is widely used in parallel-to-serial conversion, data routing, Boolean function generation, and address decoding within TTL-compatible logic systems.

Key Features

• 1-of-8 line data selector/multiplexer (8-to-1 MUX)
• 8 data inputs (D0-D7) with full on-chip binary decoding
• 3 binary select lines
• Complementary outputs: true (Y) and inverted (W)
• Active-low strobe / enable input for cascading and output expansion
• 74LS low-power Schottky TTL technology
• Nominal 5 V supply operation (recommended 4.75 V to 5.25 V)
• Typical average propagation delay (data input to W output) approximately 12.5 ns
• Commercial operating temperature range 0 °C to 70 °C
• 16-pin DIP (PDIP) package

Applications

• Parallel-to-serial data conversion
• Data routing and bus multiplexing in TTL logic systems
• Boolean function generation from a single package
• Address and channel selection / decoding
• Legacy and retrofit equipment maintenance and repair

Why Source XD74LS151 from Pacific Component Xchange

The XD74LS151 is a Xinluda-branded part with limited authorized-distributor coverage, which can make it difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and end-of-life logic, power-management ICs, and optocouplers, helping engineers and procurement teams locate parts that are scarce or no longer carried by franchised distributors.

Every order is backed by our commitment to authenticity and quality verification, and we ship globally to support production lines, prototyping, and legacy-system maintenance worldwide. Because this is a Request-For-Quote item, pricing and lead time are confirmed per order based on quantity and availability.
